We’re looking for a senior full-stack engineer to join greenfield product development on a new AI-powered revenue cycle management (RCM) product — built on a platform that moves dental records and imaging (CBCT, DICOM) between general practices, specialists, and dental schools. The engagement is fractional and milestone-based, with a quick sprint cadence and no fixed working hours — work is measured by shipped features and merged PRs. It can grow into a larger ongoing commitment as the product scales.
Your responsibilities will include: * Building full-stack features in TypeScript / Node.js (Express, MySQL, Redis, Zod) and React 18 (Vite, TanStack Query, Tailwind); * Integrating LLMs into product workflows — we build with Claude — including model harnesses, structured outputs, and data pipelines; * Working with structured healthcare data and claims flows; * Submitting PRs to dev and passing the same review and CI gates as the core team (GitHub Actions, dev → staging → prod).
What we expect from you: * Senior-level full-stack TypeScript / Node.js experience; * Hands-on AI / LLM integration experience in production; * Strong React product UI skills; * Experience with data pipelines and structured data; * Strong English; ability to self-manage as an independent contributor; * Daily use of AI tooling (Claude, Cursor) in your workflow; * US healthcare / claims / RCM domain experience; * HIPAA / PHI handling experience.
We offer: * Interesting product challenges at the intersection of healthcare data and AI; * Work in a small, focused founding team with a modern, AI-native development practice; * Flexible fractional engagement — outcome-driven, no fixed hours, fully remote; * Milestone-based cadence with room to grow into a larger ongoing commitment; * Lack of bureaucracy and direct collaboration with the founding team; * Trial period to validate the fit before scaling up the engagement.
